Graft copolymerization of nylon 6 with methylmethacrylate and methylacrylate, I. Optimum conditions of grafting and thermal behaviour of the copolymers

Abstract

Abstract Nylon 6, 20 denier, monofilaments were grafted with methylmethacrylate and methylacrylate using ceric ion/sulphuric acid as initiator. Grafted nylon samples with different % graft‐on were prepared by varying the reaction conditions. The thermal stabilities of these grafted samples were compared with parent nylon using dynamic thermogravimetry in air at a heating rate of 6 °C/min up to a temperature of 550 °C. The initial decomposition temperature (IDT) integral procedureal decomposition temperature (IPDT) and activation energy (E) values indicated that thermal stability decreased as a result of grafting.
